Is there a way to compute this sort of thing for other antenna/feedline combinations ?

For example, I have a 43 foot monopole with 63 radials, using 45 feet of LMR-400 coax transmission line. Is there a simple formula or relationship for this sort of thing ? Is it just a question of feedline length to antenna wavelength or something that counts. (I am presuming, without knowing, that the considerations for a 40 dipole might be different from a 43 ground plane antenna.)

Happy Trails.
